BOAT-PROPLLR.

SPECIFICATION forming part of Iletters Patent No. 650,613, dated May 29,1900.

Application flledebruary 26, 1900. Serial No. 6,568. (No model.)

To all whom it may concern/f Be it known that we, MACK L. ROE and JOHNT. MILLS, citizens'of the United States, residing at Bronson, in thecounty of Branch and State of Michigan, have invented a new and usefulLighting Boat Propeller, of which the following is a specification.

The invention relates to improvements in boat-propellers.

One object of the present invention is to improve the construction ofboat-propellers and to provide a simple and comparativelyi nexpensiveone adapted to be readily applied to an ordinary row-boat and capable ofready adjustment to enable the paddle-blades to he readily set forstriking the water properly whether the boat be lightly or heavilyloaded.

A further object of the invention is to enable the paddle-blades atopposite sides of the boat to be operated independently of each other,so that the boat may be guided by the propelling mechanism without theuse of a rudder.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a boat provided withpropelling mechanism constructed in accordance with this invention. Fig.2 is a longitudinal sectional View of the driving mechanism. Fig. 3 is avertical horizontal sectional view of the propelling mechanism of onesideof the boat on the line 3 3 of Fig. 2. Fig. 4. is a detail sectionalview on line 4. 4 of Fig. 2. Fig. 5 is a sectional View on line' 5 ofFig. 1.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

1 1 designate vertically-adjustable standards mounted on the exterior ofa boat 2, at opposite sides thereof, and provided with upper and loweradjustable bearing-boxes 3 and t, receiving upper shafts 5 and lowershafts 6. The upper shafts are provided with crankhandles 7 and carrysprocket-wheels 8,- which are connected by sprocket-chains 9 with lowersprocketpinions 10. The lower sprocketpinions 10 are keyed or otherwisesecured to the inner ends of the lower shaft 6, which extend outwardthrough bearings of rectangular frames 11, forming guards forpaddleblades 12 and supporting the lower shafts.

, The frames 11, which are located at the y outer faces of thestandards, are arrangedl substantially in a horizontal position and aresupported by guy-rods 13 and 14., extending forward and rearward at theends of the frames, at the outer sides thereof, and con-gv nected withthe sides of the boat, near the bow and stern, as clearly shown in Fig.1..'

The guyrods 13 and 14. are composed. of sections connected at theirinner ends by turnbuckles 15, adapted to adjust the said guyrods,whereby the rectangular frames 11 are properly supported.

rlhe vertical standards are supported in an upright position by frontand rear inclined guy-rods 16 and 17, connected with the standards atthe upper ends thereof and with the front and rear portions of theframes at the inner sides thereof, as clearly shown in Fig. 1 of thedrawings.

In order to enable the paddle-blades to be readily adjusted to operateonthe water properly when the boat is lightly or heavily loaded, thestandards are adapted to be raised and lowered and are secured betweentheir ends adjacent to their centers to the sides lof the boat by clamps19 and are provided with longitudinal openings 20, which may be formed.in any suitable manner. The clamps 19,whicl1 are mounted upon the boat,extend through the slots or 'openings 2O of the standard, and areprovided with nuts or other suitable clamping devices wherebythestandards are held at any desired vertical adjustment. The guyrods arepreferably movably secured to the sides of the boat by thisconstruction, and by means of their turnbuckles they may be readilyadjusted to support the standards firmly in their adjusted position.

The paddle-blades, which are clipped or otherwise secured to the lowershaft, are preferably pointed, as shown, to enable them to enter thewater readily and leave the water with the least resistance. When thecrankhandles of the upper shafts are rotated, motion will becommunicated to the lower shafts and the boat will be driven through thewater, as will be readily apparent, The pro IOO ` porting the extendedshaft and receiving and `and adjustably mounted on the exterior ofpellingdevicesof the opposite sides ofthe boat are adapted to beoperated independently of each other, and by this means the boat may beguided without a rudder., A y

It will be seen that the boat-propeller is exceedingly simple andinexpensive in construction, that it is easily operated, and that thepaddles may be adj usted vertically to suit the position of the boat inthe water, so'that they will strike the latter properly and operate tothe greatest advantage. M What we claim is* -f v 1. In a propeller forboats, the Acombination with aboat, of astandard adj ustably mountedthereon and adapted to be raised and low ered,` said standard beinglocated on the ex-v terior of the boatand provided with bearings, shaftsjournaled in the bearings, one of the shafts being extended outward andlocated ata point below the upper edges of the boat, gearing connectingthe shafts, blades mounted on the extended shaft, and a frame supforminga guard for the blades, substantially as described.

2. In a propeller for boats, the combination with aboat, of a verticalstandard pivotally the boat and adapted to be raisedor lowered, meansfor supporting the standard in its adjustment, upper and lower shaftsjournaled in suitable bearings of the standard, thelower the boat andextended and provided with blades, gearing connecting the shafts, andmeans for operating the upper shaft, substantially as described.

. tiallyas described.

with a boat, of a standard arranged at the exterior of the boat,adjustably secured to the v saine and capable of being raised andlowered upper and lower shafts journ aled on the standardrthe lowershaft being located .at a poin t below the upper edges of the sides-ofthe boat and extended outward and provided with blades, a frame arrangedat the bottom of the standard and supporting the extended portion of thelower shaft, and guy-rods connecte'd withthe frame and with the top ofthe standard `':Mld*secured to the boat, substan- Yif. In a propellerfor boats, the combination with a boat, of' a standard pivotally andadjustably secured tothe exterior of the boat and adapted to be raisedand lowered, upper and lower shafts journaled on the standard, the lowershaft being located at a point be low the upper edges of the sides ofthe boat and being extended outward, sprocket-gearing connecting theshafts, a frame mounted `on the extended portion of the lower shaft,l

blades secured to the lower shaft and operat-g ing within the frame, andguy-rods supporting the frame and the standards, substantially asdescribed.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in the presence of two witnesses.
